"Revolvers!" exclaimed our hero at once. "Tomkins, I think there were two revolver shots then. Eh?"

The man nodded; he had hardly time to speak.

"Guess so," he said abruptly. "Revolvers--those villains we're after.

They've set a whole crowd on to us."

"Then the sooner we are out of their reach the better. See here," cried Jim; "try to find out where those particular ruffians have got to and pepper them. Sam, get to the wheel; we'll make over to the far bank; that'll bother them."

The motor buzzed and roared as he switched his levers forward, while the water pump gathered such power from the momentum that the pressure within the jackets increased wonderfully. Ching, despite all his efforts and all his cunning, could no longer seal that rent made by the bullet.

True, he reduced the leakage wonderfully; but from all round the margin a spray of hot water swept broadcast, quickly drenching our hero to the skin. It was a trifle, however: Jim congratulated himself that he was not likely to be scalded.

"With a motor on a car ash.o.r.e it would be different," he told himself, as he put the launch in motion. "Here the temperature cannot very well rise too high. She takes in her supply direct from the river, and pumps it right through the jackets and out again. Swing her over, Sam. See here, Tomkins, I'm going straight for the far bank, and will swing round in a circle when I get near. We'll bring up end on, beneath a tree if possible; then we shall present less of a mark. Ah! Good shooting!

That'll make 'em careful."

As yet he had had no time in which to reckon the odds opposed to them, nor the imminence of the danger in which the expedition stood. Minor matters occupied his attention, those and vague queries as to how he should proceed. He noted with satisfaction that Tomkins and his two comrades were making excellent practice. At least half a dozen of the enemy had already fallen.

"Round with her, right round, Sam," he commanded, when the launch was near the bank. "Steady! Back her! How's that for a tree?"

With Sam aiding him at the wheel, and he himself controlling the pace of the launch, Jim soon manoeuvred her beneath a tree which swept its branches right into the water. Then he threw his lever out, slowed the motor, and crawled into the cab. With Tom's help he laid the Major on his back and carefully searched for a wound. And very soon they came upon the result of the bullet. There was a huge, discoloured b.u.mp on the top of his head, while an ugly graze crossed the forehead. For the rest, he was breathing deeply and regularly, while the pupils were equal.

"Bullet knock de sense clean out ob him head," explained Tom, as if he were completely conversant with the matter. "Knock de Ma.s.sa Major silly.

To-morrow, when he wake up and come to himself, he hold de hands to him head. Oh, how him ache! Him feel more silly den dan he look now. But, Ma.s.sa Jim, dis a bit ob hot stuff. Dis quite all right. Once de fun begin Tom like it hot and plenty. Yo bide little bit; soon dem debil fire away all dere powder and ball. Den time to make a move; den Tom hab someting more to say about de wound. Yo see dat!" and he held out a bruised and swollen hand for Jim's inspection; "sc.u.m of a black n.i.g.g.e.r do dat. Yo see. Tom not forget when de time come."

Really the big fellow was too much for Jim. Grave though the situation was, he was forced to laugh again. For Tom did not stop at threats; his words lost all their impressiveness without the gestures. And the latter, terribly fierce though they were--for when he bared his teeth in a snarl no one could look more like a demon than Tom--were instantly banished and forgotten by the fellow's well-known merry smile. Tom's six-foot smile was too catching. His comical face never failed to draw laughter from his audience.

"If you stand up and expose your ugly head like that you won't be left when the powder has been done with!" exclaimed Jim severely, suppressing his mirth. "Now, listen to this: Tom will watch up stream, Ching will keep a lookout in the downward direction, while Sam will hop ash.o.r.e.

Don't go more than a few feet away, lad," he warned the little negro.

"Just enough to keep us from being surprised, and to allow you to rejoin instantly. Say, Tomkins, supposing we give over firing?"

A flushed face turned towards him, while the policeman regarded our hero as if he thought him demented.

"Let 'em go on shootin' and not answer!" he gasped. "Why, of all----"

"It's like this," explained Jim curtly. "All the time you fire they know where we're lying. I don't say we're likely to get bad wounds at this distance, for most of the weapons yonder are gas barrels, I reckon, but a revolver bullet might hit by accident, and then it'd be a case with one of us."

There was indecision on Tomkins's face for the s.p.a.ce of a few seconds.

To tell the truth, though an excellent fellow, he was one who boasted unusual independence, both in word and act, and while it was a fact that he had suggested that Jim should take the Major's place, he had taken it for granted that orders from our hero would not be very frequent, and that he would mainly direct by managing his motor, and seeing that a course was steered. And here he was fighting the vessel. There was something approaching a scowl on Tomkins's face as the thought flashed across his brain. He swung round to look at the enemy. But a second later he was glancing up at Jim once more, his weapon idle beside him.

"You're a conjuror, I guess," he said abruptly. "I'd forgotten those revolvers. I thought your suggestion was a bad one; then, blessed if one of them rascals didn't drop in a shot. Look there! He winged me!"

He grinned as he held out a finger of his left hand for inspection.

"That's what I got for being foolish. You're right, sir," he said with decision. "What next?"

"See that you don't touch the branches overhead. They'd see them moving from the far side. Sam there? Come aboard. Now," he went on, when the negro had dropped into the well of the launch, "not a sound from anyone.

They won't hear the motor while she is running light. We'll run down stream under the trees, and then make a break into the open. A hundred-yards start will allow us to laugh at all their weapons."

There was agreement on all the faces about him. Tomkins nodded very decidedly, showing that the plan met with his approval.

"Then lie out there right forward, Tom," said Jim, lowering his tones.

"Those long arms of yours will do as fenders. Push us off if we get too near to a tree. But don't touch 'em if you can help it. Get on to that wheel, Sam; I'm moving off at once."

He threw in his lever and set the propeller turning very slowly, but the launch felt the effect instantly. She was already heading in the right direction, and at once began to glide away beneath the leafy covering.

It happened, too, that she was able to pursue this course for more than a hundred yards before a break in the bank, where there had been a species of landslide, and where the trees receded sharply, caused her to come into the open.

"Take her clear into the centre, and then head her for the lagoon," said Jim, calling gently to Sam. "Tom, slip back into the cab. All hands keep their heads as low as possible. Don't fire a shot unless there's actual need, and if there's trouble, let every man who has no other special duty pepper those rascals for all they're worth. Over with her."

Bizz! gurr! gurr! The motor roared at his bidding, while the propeller lashed the shallow water into foam. Ching grabbed at the covering placed over the rent in the water jacket, and then turned his face from the engine. For, though there was nothing there to harm one, still the spray forced in all directions by the pump was disagreeable, to say the least of it, and made seeing almost impossible! Bizz! Gurr! the launch shot down the last few yards of the dark lane beneath the trees. Sam, his eye fixed on the opening, swung his wheel right over, while Jim nudged his levers a trifle higher. The planks at his feet had started to dither again, and practice told him that the vessel must be moving. But they were not shaking and vibrating to such an extent as to make standing upon them uncomfortable. There was no need for such an exhibition of haste yet awhile.

"Might bust the jacket altogether," Jim told himself. "Might have a bad breakdown. Better get along as we are. I can squeeze a little more out of her if there's occasion. Ah, here she goes round into the open!"

Turning abruptly, as Sam swung the wheel over, the launch canted on her heel till a stream of water swamped far up the rail-less deck astern.

The bows lifted from the surface in spite of Tom's enormous weight, while a big bow wave collected beneath her cut.w.a.ter, and, gathering in size as the propeller shot the boat forward, was presently spreading across the surface of the river, and washing heavily against the nearest bank. Straight as a dart the vessel was directed to the point that Jim had mentioned. She cut obliquely across the stream, and, almost before those aboard could have believed it possible, was heeling again to the swerve of her rudder.

"Done them brown. Cut out below them, and left 'em well behind. Boys!"

cried Tomkins, beside himself with delight, "I 'low as we've something to thank the chief for. He's done a cute thing; he's stolen a real march on them blackguards."

"Not know so much, siree," answered Tom from his post in the cab, where he had retired at Jim's orders. "Ma.s.sa Jim all right, don't you fear. He know right well what him up to; but what yo say to dat, and to dat? Dem bullets buzz too close fo Tom's likin'."

That the pa.s.sage of the launch had been observed there could not now be a shadow of doubt, for the far side of the river had already displayed several patches of smoke, billowing from the rifles of the enemy. But Tomkins laughed at the idea that they could prove harmful.

"Jest you squat right down here at my feet, darkie," he laughed. "Then you won't have no cause to get wonderin' whether a bullet's coming along. Fer me, I guess as we're well out of a ruction that looked at one time likely to get too hot fer anything. You ain't got sich a thing as a light along of you?"

Tom grunted. It annoyed the big fellow to have a recommendation to place himself in safety. His eyes gleamed white in the morning light; his sharp teeth gritted together.

"Yo policeman," he said, as he extracted his pipe from his pocket, and still leaned on the edge of the cab, within full view of those on the bank of the river, "yo Tomkins, yo ain't the only one as wants a smoke.

By gum, but Tom like a draw too, 'specially early in de mornin', when dere a chance of gettin' a bullet. Yo sit right there and wait. Matches ain't so plentiful in this locality."

He stuffed his pipe methodically and slowly. Then he put the stem between his teeth and, slowly again, struck one of his matches. He was on the point of offering the light to the policeman when a sudden exclamation came from Sam.

"Look dar!" he shouted. "Not tink dat good for dis here party. Tings is all changed round. Dey's chasin' us instead of we bein' after dem. Ma.s.sa Jim, dis am a bit of a conundrum."

Conundrum or not, the situation was sufficiently serious. Even Tomkins went red and hot as he realized to the full the gravity of this new movement. For the motor launch was not the only one on the river. The launch on which the two ruffians had escaped from Colon, and which they themselves had chased in the late hours of the previous night, was now chasing them, but under altered circ.u.mstances. There were fifty dark figures swarming over her decks.

"Right straight down the centre!" cried Jim, waving to Sam. "You hold on dead straight unless I give you an order. I think we shall just clear her."

But would they? That was the question. The steam launch which had disappeared so mysteriously on the previous night had suddenly darted out from the opposite bank of the river, her decks crowded with men.

Moreover, she was fully prepared for a speedy journey, for steam was hissing and whistling from her escape. There was a white wave under her foot, a spreading surf behind her, while the course she followed promised to bring her alongside Jim's vessel before the latter could make her way down the long stretch of water that led to the lagoon.

Indeed it looked very much as if the stranger would intercept their pa.s.sage, and then--what was the prospect?

"Boys," called out Jim after a minute, during which time he had pushed his throttle and ignition levers as far forward as was possible, "see here, boys, there may be a tussle before us. Get to work right now with your rifles. Give it to 'em hot. We may be able to scare 'em."

Pip! Pop! The sharp reports of the Government rifles punctuated the semi-silence which followed, while screams of rage came from the crowded decks of the enemy. Pip! Pop! Tomkins and his friends splashed their bullets in the centre of the throng, and sent more than one of the dusky warriors rolling. Meanwhile, under Jim's guiding hand, the motor launch sped faster towards the lagoon, till her whole frame shivered and vibrated. In such acute cases a second's s.p.a.ce of time will change the complexion of matters entirely, will advance the fortunes of one party against those of the other. And here there was an ill.u.s.tration of the fact. Jim's engine raced madly, while the propeller took a firm grip of the water. The vessel bounded forward at a pace which easily outdistanced that of the steam launch. Very soon it became apparent that Jim and his friends would slip past the launch that was steaming from the opposite bank to intercept them.

"Keep at it with those rifles, boys!" he shouted, delighted at the turn matters had taken, and, heedless of the spray of water which gushed in all directions from the rent in the cooling jacket of the motor. "Keep down their fire, and if you catch a sight of those rascals, pepper them properly. Hooray! We'll best 'em yet."

"Run past dem as if they was lame and walking," sang out Tom, bubbling over with excitement. "Den turn and gib dem what fo. Yo tink dat good advice, ma.s.sa. Yo do as I say; den we knock dem into little pieces. Tom able to find de blackguard dat fired dat shot; den smash um to a jelly."
